LMZ31707: Request for thermal resistance Information for Junction-to-case (θJc)

Jonathan Geronga

Part Number: LMZ31707

Hi Team,

We have a customer requesting for the thermal resistance Information for Junction-to-case (θJc) of LMZ31707RVQT (RVQ package drawing).

Please let me know if you have the information we can share with the customer.

Thanks!

Hi Jonathan,

The datasheet has the ψJT value, which is often the more practical value to use for thermal estimations (please read Section 3 of this app note). Would that work for the customer?
